Measuring interaction effect by fix design in CBC

Hi,

Assume I have 4 attributes each with 4 levels. I have made an alternative design (fractional factorial) that is able to measure two way interaction between attribute 2 and attribute 4. Is there any method of choice set design for fixed task, which can measure interactions? The method of analysis is HB.
If I use BIBD how can I check that this design is suitable for measuring above interaction?
Thanks for you support

Yes, there are several ways to make the choice set design based on your fraction that supports the two way interaction of interest.  I see that you've sent me a private email message as well and I'll reply to that later today with some references you can use to make your design.
